2 Derivation of the new delayed logistic equation We derive our new delayed logistic equation by considering the mean- eld limit of a simplistic agent-based, on-lattice model that describes both cell motility and pro-liferation, and cell-cell interactions through the incorporation of volume exclusion.

We have written a new equation to study the statistics of earthquake distributions. We call this equation “the generalized logistic equation”. The Gutenberg-Richter frequency-magnitude formula was derived from the solution of the generalized logistic equation as an asymptotic case for the approximation of large magnitudes.
